I suggest you had better not, because as we all know that the 3D glasses must be used to the 3D images, if you just wear the 3D glasses outside, then you will feel confused. Because the light that gets through the surface is mostly of one polarization, and any others are reflected back in and never get out, so will see the building and other things outside strange. Now you know wearing 3D glasses outside is not bad for your eyes, but pls remember that you cannot wear 3D glasses outside when it is sunny, because the 3D glasses are not like the sunglasses that can protect your eyes from the sunshine. Otherwise, the sunshine outside will strain your eyes, then your eyes are easily get hurt because of the sunshine. Before using the 3D glasses, you can read the warning tips so that your eyes will not be hurt.
